Show me where what he did was illegal. I've provided a link to prove to you what he did was not in my post #7.
He's certainly a hypocrite, which is what we should be calling him on. The AR-15 with the 30-round mag wasn't the only thing he wanted to buy. He actually purchased a 1911 in .45 ACP, as well. He took it home that very day, presumably after completing a 4493 for that purchase.
